These are all nasty programs that will not only slow down your computer, they will literally take over the functioning of your computer. You definitely don't want any of these parasite programs on your computer.
To get rid of these parasite programs, and to prevent them from installing in the first place, you need up-to-date firewall, anti-virus, and spyware removal programs.
These are three separate software programs that must be running at all times except for when you are not plugged into the Internet. It is very important that these programs continuously update themselves or they will become out-dated and will no longer be useful.
We recommend the full featured antivirus program McAfee Internet Security 2013 features a first rate antivirus checker, malware remover, and firewall, and even lets you make a rescue CD for when your computer can't boot Windows.

Every Pentium-class and newer computer has fans and heat sinks specifically for cooling the CPU. When the fan wears out or becomes ineffective because it's clogged with dust or other debris, the temperature of the CPU rises. In most cases, the computer simply stops operating, but in some cases, the whole computer will appear to be running slowly or taking long pauses.
Often this happens because the CPU is repeatedly locking up for a few seconds at a time. Sometimes it happens when the CPU is running just hot enough to affect its performance but not hot enough to lock up. Clean the CPU fan so it spins at the proper rate, clean out the heat sink so it dissipates heat properly, or replace the fan/heat sink unit.
Old or conflicting Windows device drivers
An example would be you might actually have two entirely different video drivers on your system and Windows could actually be alternately using both of them.
To prevent this problem, First boot the computer in Safe Mode by pressing and holding the F8 key during startup, after the DOS memory check has completed. While in Safe Mode select Start/Settings/Control Panel/System/Devices. Click on all the devices and see if the various drivers have any yellow or red exclamation marks (which indicates a driver conflict) and also determine if there are any duplicate drivers that can be eliminated. You may have to delete and reload a driver to correct these problems. Duplicate drivers can and should be deleted.
